Bold of you to assume total destruction of btc. Wealth is the things in life, not the money. Money is just the means to the end. No money " is just a chart". If you have a million dollar farm and another a million US dollars. The society breaks, what does the person holding the dollars have? Nothing. The one with the farm still has a farm. I get your point here, but pure monetary instruments like bitcoin are a better money because of this purity. My holding of it doesn't deprave others of its utility ie. Houses, gold, silver etc. Any other money we've had as a civilization always has other use cases which in turn get priced out once the good carries a monetary premium.
